I have posted some code that uses the every_n_millis from the FASTLED library. I have looked at the documentation and cant find mention of it anywhere. What i would like to do is have the 0-6 pixels run in order and the 13-7 pixels run in reverse order.(two Neopixel jewels daisy chained). I am not against splitting the pair and using separate pins and separate functions. I wish to avoid delay as this will be part of a larger sketch. This appears to be a nice bit of clean code for my needs.
Two jewels:
// EVERY_N_MILLIS used to replace delay by Chemdoc77
#include "FastLED.h"
#define NUM_LEDS 7
#define DATA_PIN 5
#define LED_TYPE NEOPIXEL
int brightness = 30; // Adjust from 0 to 255 to set brightness.
uint8_t x=0;
CRGB leds[NUM_LEDS];
void setup() {
delay(2000); // power-up safety delay
FastLED.addLeds<LED_TYPE, DATA_PIN>(leds, NUM_LEDS);
FastLED.setBrightness(brightness);
FastLED.setMaxPowerInVoltsAndMilliamps(5, 1000);
set_max_power_indicator_LED(13);
fill_solid(leds, NUM_LEDS, CRGB::Black);
FastLED.show();
}
void loop() {
CD77_colorwipe_dot_nodelay (CRGB::Red, 100);
}
//===================================================
void CD77_colorwipe_dot_nodelay(CRGB color, uint32_t wait) { //without delay
EVERY_N_MILLIS(wait){
x++;
if (x >= NUM_LEDS) {x = 0;}
fill_solid(leds,NUM_LEDS, CRGB::Black);
leds[x] = color;
FastLED.show();
}
}
void CD77_colorwipe_dot(CRGB color, uint8_t wait) { // with delay
for (uint8_t i = 0; i <NUM_LEDS; i++) {
leds[i] = color;
FastLED.show();
delay(wait);
leds[i] = CRGB::Black;
FastLED.show();
}
}
